Porcelain fused to metal crowns have been considered the gold standard for repairing damaged teeth. This design type has been used for countless years. These crowns are cast metal with a porcelain covering atop it. The tooth-colored ceramic is baked on top of the metal alloy base, which makes it stronger. The metal is thin yet still strong and fits perfectly over the tooth. It is made to look exactly like a natural tooth. The porcelain layer is durable and can withstand chewing from opposing teeth.
